Subject:	SGP/SMOS/E20 - 6-month Calibration Checks
DataStreams:	sgp1440smosE20.b1, sgp1smosE20.b1, sgp30smosE20.b1
Description:	During the time periods specified, the SMOS.E20 tower was lowered for 6-month Calibration Checks. During these times wind data are incorrect and temperature and humidity data may be incorrect. Note, exact times when tower was down or maintenance was being performed is sometimes unknown. Users should use the remaining data from these days with caution. Calibration results are available from the OMIS database at http://www.ops.sgp.arm.gov:591/smos6cal/default.htm To view all 6-month calibration reports leave the date time entry blank.

Subject:	SGP/SMOS/E20 - RH values suspect
DataStreams:	sgp1440smosE20.b1, sgp1smosE20.b1, sgp30smosE20.b1
Description:	Recently, the RH readings at this facility have been very high (sometimes approaching 110%) in saturated conditions. This is especially prevalent from 01/03/2005 through 02/07/2005.

Subject:	SGP/SMOS/E20 - Sensor failure
DataStreams:	sgp1smosE20.b1, sgp30smosE20.b1
Description:	Wind direction values were nearly constant around a value of 15 degrees. Problem was caused by a lightning strike which damaged the sensor.
